Abstract (en)
[origin: EP0701309A2] A semiconductor laser diode which can be applied to optical fiber amplifiers to attain a high reliability and can generate light having a wavelength of about 1 mu m is provided. This semiconductor laser diode is formed on a GaAs substrate and has an active layer comprising a GaInAsP strained quantum well whose energy band gap is smaller than that of GaAs. Barrier layers each comprising GaInAsP whose band gap is greater than that of the active layer are bonded to the active layer through heterojunction. According to this structure, when the active layer and the barrier layers are grown, the amounts of supply of a Ga material and an In material can be controlled in a simple manner and a semiconductor laser diode having a high reliability can be realized. <MATH>
